leschreibunr und Erläuterung zur Patentanmeldung 'Verfahren für filternde Abscheider zur trockenen Chenisorption'Description and explanation of the patent application 'Process for filtering separators for dry Chenisorption'

Die Anlagerung von Schadstoffen in Abgasen an trockene Chemisorptionsmittel wird in jüngerer Zeit vielfach angewandt.The accumulation of pollutants in exhaust gases on dry Chemisorbents have recently been widely used.

!•[asse Verfahren bringen vielfach ein Abwasserbelastungsproblen, trockene Verfahren können vielfach durch Pelletisieren nit Bindectoffen der Abfallprodukte so verfestigt xverden, daC sie einer Derionie übergeben werden können, un einer Auslaugung, durch. Grundwasser und/oder Regenwasser zu widerstehen.! • [as these processes often cause wastewater pollution problems, Dry processes can often be solidified by pelletizing the waste products with binding agents xverden that they will be handed over to a derionie can, and a leaching, by. Groundwater and / or Resist rainwater.

Um größtmögliche Wirkungsgrade in der Chemisorption zu erzielen, sind Vorrichtungen bekannt geworden, die gekennzeichnet sind durch Reaktorstrecken in der Eontaktstrecke und durch naßabscheidende Filterabscheider in einfacher oder doppelter Abscheideausführung.In order to achieve the greatest possible efficiency in the chemisorption achieve, devices have become known which are characterized by reactor sections in the contact section and through wet separating filter separators in a single or double separator design.

Filterabscheider bekannter Bauweise, die durch Rüttelung oder auch durch Luftschock gereinigt werden, sind in der bekannten Konzeption nicht zweckdienlich geeignet, um als Endsystem einer Abscheidung den größtmöglichen Wirkungsgrad zu garantieren.Filter separators of known design, which are cleaned by vibration or by air shock, are in the known conception not expediently suited to achieve the greatest possible efficiency as the end system of a separation to guarantee.

um den Durchlaßgrad zn minimieren, wird erfindungsrei.iäß vorgeschlagen, Filterabscheider für die Ohe\isorption
au verwenden, bei denen die ITiItorfl"eher höchstens für 1 Mg 2 ;ί der Geoa::;tfilterfläche in ^roinigungsprozeß
stehen und diese Eilterfläche vorzugsweise Tor der .'eaufschlagung mit Schadgasen zuerst nit trockenen Chenisorptioncirasnen beaufsclilagt wird, bevor die zu reagierenden und abzuscheidenden .Schadstoffe die FilterflLlclie beaufschlagen«,In order to minimize the degree of permeability zn , it is proposed according to the invention, filter separators for the absorption
au use, in which the ITiItorfl "rather at most for 1 Mg 2; ί of the geoa ::; t filter surface in the cleaning process
stand and this filter surface is preferably the gate of the exposure to pollutant gases is first exposed to dry Chenisorption Cirasnen before the pollutants to be reacted and separated act on the filter filler ",

Dieses '.-.rird in einfachster Veise dadurch ersielt 9 indera nan z.B. ein Filtersysten nimmt, in den 100 einseine
j?iltertaGchen eingearbeitet sind, und wobei jeweils nur eine Filtertasche oder· ein Filterschlauch durch Schocl:- oder andere "Vorrichtungen, gereinigt wird, das effektiv

j? iltertaGchen are incorporated, and in each case only one filter pocket or · a filter hose is cleaned by Schocl: - or other "devices, which effectively
at least 99 % of the total filter area is continuously exposed to the chemisorption process »

Bei Grofianlagen läßt sich diese Überlegung selbstverständlich auch auf z. B, 2oo und mehr Einseieinheiten aufbauen.This consideration can be taken for granted with large systems also on z. B, 2oo and more units of one set.

Werden die" Anlagen so groß? daß mehrere loo Filtereinzeleinheiten erforderlich sind, so wird xfeiterhin erfindungsgemä£ vorgeschlagen, daß die prozentuale Abschaltung und Eeinigung aus dem Gesamtsystem so vorgenommen wird, daßIf the "systems are so large " that several hundred individual filter units are required, it is further proposed according to the invention that the percentage shutdown and cleaning of the overall system be carried out in such a way that

nach der Abreinigung das abgereinigte Filtersystem mit frischer Ghemisorptionsmasse beaufschlagt wird, bevor der Chemi Sorptionsprozeß, d«.h. das Zuführen von Schadstoffen, geschieht.After cleaning, the cleaned filter system is treated with fresh hemisorption mass, before the chemical sorption process, i.e. feeding of pollutants, happens.

In der beiliegenden Zeichnung ist die erfindungsgemäße Anordnung dargestellt:The arrangement according to the invention is shown in the accompanying drawing:
